The only things that have change are that he is in a different stall and ridden in a much larger arena. A bunch of us moved together so he is still getting turned out with the same horses he was out at the old place. He is also getting the same feed with the same supplements other then getting flax added. I never thought about ulcers, I guess because the vet and my trainer never said anything about that. He has become girth sour and gets cranky when I do it up that started tho before we moved. Is that a sign of ulcers?
